JAMES BENTON, OF EAST PALESTINE, OHIO.

VENTILATOR FOR BUILDINGS.

To all whom it may concern.'

Be it known that I, JAMES BENTON, a citizen of the United States of America, residing at East Palestine, in the county of Columbiana and State of Ohio, have invented certain new and useful Improvements in Ventilator's for Buildings, of which the following isaspecilieation, reference being had therein to the accompanying drawing.

This invention relates to improvements in ventilators for buildings, and the invention has for its object to provide a novel ventilator for r'emoving the irnpur'e air of the numerous compartments of a building, the ventilator being constructed to insure a strong dral't to the exterior of the building, wlrer'eby Vthe numerous conrpartnrents of the building will be thoroughly ventilated and aired.

My-improved ventilator' can also be used asa lig'lrtning condrrctor', and pr'esents a neat appearance upon the exterior of aA building. The ventilator' is constructed of a plurality of sections, whereby it can be used in connection with a building having a plurality of floors or compartments arranged one above the other.

p The simple construction of the ventilator permits of its easy installation, and at the same time reduces the expense of manufacture.

The detail construction entering into the invention will be presently described and then specifically pointed out in the app ended claims.

Referring to the drawing forming a part of this specification, Figure l is an elevation of a ventilator Fig. 2 is a vertical sectional view of the same, Fig. 3 is an elevation of a ventilator serving functionally as a lightning conductor, Fig. 4 is a detail sectional view of the ventilator. Figs. 5 and (i ar'e detailed views of a modified form of damper used in connection with a ventilator.

A ventilator in accordance with this invention comprises a pair of bell-shaped castings l, 2 and an inverted bell-shaped casting 3. The casting l has a perforated bottom G, the casting 2 has also a per'forated bottom l0 and is further provided with a depending irrter'ior'ly screw-threaded nipple ll. The nipple ll is connected with the casting l through the medium of a hollow tubular member 4, said member at its lower end being interiorly-screw-threaded and receiving the upper' end of the casting l. The upper end of said member' 4 is exteriorly screw-threaded, such threads engaging with the threads of the nipple ll.

The casting 3 has its top perforated as at 'I7 and extending from the top of the casting 3 is a projection 18 recessed as at 19, the latter' receiving a centrally-disposed depending lock 20 carried by the mushroom shaped cap 2l. The lower' end of the casting 3 is exteriorly scr'ew-tlrr'eaded and the upper end of the casting 2 is exteriorly scr'ew-threaded and engaging the Specication of Letters Patent. Application fired June' 12, 1907. serial No. 378,522.

Patented ocr. 29, 1907.

said exterior threads is an interior'ly-thr'eaded coupling collar 5, the latter connecting the casting 2 with the castin g 3.

lo control the dr'aft through the ventilator, the tubular member' 'L is provided with a conventional form ot' damper 22, either operated by a handle 23 or by a depending llexible member 24. The flexible member 24 is used when the damper is positioned in close proximity to the ceiling of the compartment through which the ventilator' passes.

When the ventilator' is in position, the casting lis adapted to lit in the floor 7 of a building S and ventilate the compartment 9 beneath said floor, while the casting 2 is secur'ed to the ceiling l2 of the compartment by hold-last devices l5, which pass through the perimeter of the lower' portion of the casting, the tubrrlar menrber Ll extending through the cornpar'tment f4. The casting 3, however', is mounted in the roof 16 of the building S and the cap 2l extends above the roof 1G.

In Fig. 3 of the drawings is illustrated the ventilator as a lightning conductor, the cap 2l of said ventilator being provided with a spear-shaped extension 25. 'lhe casting `l in this instance is dispensed with, and the castings 2 duplicated according to the number of floors through which the ventilator' passes, the lowermost tubular' member' 2G carried by the ventilator' extending into the basement of the building and into the ground, whereby, should lightning strike the extension 25, the electrical current will be innuediately grounded.

A modified form of danrper' is illustrated in Figs. 5 and 6, wherein a horizontal perforated shutter 30 is pivotally mounted in a spider 3l carried by the casting 2. The shutter 30 is provided with a handle 32 protruding tlrrorrglr a slot 33 formed in the lower' end ofthe funnel 2, it being necessary to make this funnel separate from the casting, in or'der' that the shutter can be placed in position.

The ventilator' is preferably located at the corner of a building and in the corners of the compartments thereof, and by the novel construction of the same, it will be observed that a strong draft is created through the ventilator capable of removing all impurities from the var'iorrs compartments of a building. I

Strong and durable metal or terra cotta is used in the construction of the ventilator, and when the pipes or tubes thereof pass through compartments, Said pipes or tribes can be finished to present a neat appearance.

Having fully described my invention, what I claim and desire to secure by Letters Patent is:

l. A ventilator consisting of a plurality of lJelLshaped castings each having a perforated bottom, a. hollow tubular member' inter-posed between and connected to said castings, an inverted bellslrrrped casting, means for' coupling the latter to one of the first-mentioned castings, said inverted bell-shaped casting havinga perforated top, and a cap supported by the top of the inverted bell-shaped casting and of greater diameter than the said casting.

2. A ventilatorl consisting of a plurality of bell-shaped 5 castings, each havinga perforated bottom, a hollow tubular member interposed between and connected to said castings, an inverted bellshaped casting, means for coupling the latter with one of the Emst-mentioned castings, said inverted bell-shaped casting having a perforated top, a cap supported by the top of the inverted bell-shaped casting 1() and of greater diameter than the said casting, and a damper mounted in said tubular member.

In testimony whereof I alx my signature in the presence of two witnesses.

JAMES BENTON.
